Split-into-two-type prefabricated pipe joint combination formwork and manufacturing method of split-into-two-type prefabricated pipe joint

Abstract

The invention provides a split-into-two type prefabricated pipe joint combination formwork and a manufacturing method of a split-into-two type prefabricated pipe joint. The split-into-two type prefabricated pipe joint combination formwork comprises a bottom formwork, an inner formwork, an outer formwork and end formworks, wherein the bottom formwork is arranged on the ground; the inner formwork isarranged on the bottom formwork and forms a closed shape in an enclosing mode; the outer formwork is arranged on the bottom formwork and arranged on the outer side of the inner formwork in a surrounding mode, and a gap is formed between the outer formwork and the inner formwork to form a filling area; and the end formworks are arranged in the filling area and comprise the first end formwork and the second end formwork which are arranged at the two opposite ends of the filling area correspondingly, the first end formwork and the second end formwork each comprise two parallelly-arranged end plates, and the two sides of the end plates abut against the outer wall of the inner formwork and the inner wall of the outer formwork correspondingly, so that the first end formwork and the second end formwork form reserved cast-in-situ areas with the inner formwork and the outer formwork correspondingly, the filling area comprises a casting area and the reserved cast-in-situ areas, and the castingarea is filled with concrete. The pipe joint is prefabricated in a split-into-two-type mode by arranging the end formworks, and the problems of production, transportation and hoisting of the large-section pipe joint are solved.

Description

technical field [0001] The invention relates to the technical field of pipe jacking pipe joint manufacturing, in particular to a two-part prefabricated pipe joint combined template and a method for manufacturing the two-part prefabricated pipe joint. Background technique [0002] Pipe jacking construction is a non-excavation construction method. Through the jacking force generated by the jacking equipment in the working pit, the friction between the pipe and the surrounding soil is overcome, the pipe joint is pushed into the soil according to the designed slope, and the earth is transported to the ground. Go, after one pipe joint has been jacked into the soil layer, the next pipe joint will continue to be jacked, so that multiple pipe joints will be pushed into the soil in turn. Large-section pipe jacking (clear cross-sectional area between 50 square meters and 100 square meters) is widely used in the construction of street-crossing underground passages, underground pipe gal...
